RULING-MACHINE.

To all whom it may concern.'

Be it known that I, GEORGE F. Mer-XMMS, a citizen of the United States,and resident of the borough ot Brooklyn, in the city and State of NewYork, have invented a new and useful Ruling-Machine, ot' which thefollowing is a speciiication.

My invention relates to ruling machines and more particularly to what Iam pleased to term striking mechanism for ruling machines, with theobject in view ot providing simple and effective means for accuratelystopping the ruling of the vertical lines on a page at the point wherethe head line crosses, or at any other predetermined point.

In the accompanying drawings, Figure 1 is a view in end elevation ot somuch ot' a ruling machine as will suffice to show the practicalapplication of my invention, Fig. 2 is a top plan view oit the same withinking rollers removed, Fig. 3 is a vertical section in the plane ot'the line A-A ot F ig. 2, Fig. et is an enlarged section in. detail takenvertically through the machine at the point where one of the liftingscrews is located, Fig'. 5 is a top plan view ot the same, Fig. G is aview in detailin elevation showing the means for holding the rack barwhich operates thc` litt-ing screws against the face ot the baroperating cani wheel, and Fig. 7 is a partial view in face elevation oitthe cam wheel at the point where the cams are located thereon.

The framework ot the machine is in general form that commonly used inruling machines and is here denoted as a whole by 1.

The roll, providedwith the ruling disks for ruling the upper side of thesheet, is denoted by 2 and its companion roll, provided with groovescorresponding to the ruling disks on the roll 2, is denoted by 3.

The roll, provided with the ruling disks for ruling the under side ofthe sheet, is denoted by t and its companion roll, provided with groovescorresponding to the ruling disks on the roll 4f, is denoted by 5.

The inking rollers are denoted, respectively, by G and 7. The tapes forfeeding the .sheets ot' paper to the machine are denoted by 8 and thosefor taking the ruled sheets away from the machine by 9.

The feeding rolls, discharge rolls, ruling disks and companion rolls,are arranged and operated in a. well known manner, subject to certainmodilications which will be here- Specicatio'n of Letters Patent.

inatter particularly pointed out, by systems of gears't'or transmittingmotion from a drive pulley 10 which is actuated from a suitable sourceot' power, not shown.

The disk carrying roll 2 otl the pair 2 and 3, and the platen roll 5 ot'the pair 4 and 5, are mounted in vertically movable bearings quitesimilar to one another, one of thesebearings being' shown in detail inFig. et and denoted by 11.

The bearing 11 is attached to a cross head 12, in the present instanceby means of a screw 13 which is screwed into the bearing 11 and isgrasped by the two sections of the cross head 12., these two sectionsbeing crowded toward each other by means of a binding screw let, seeFig. 5. This cross head 12 carries in its end, which overlaps the trame1, an adjusting screw 15 which rests on an inclined faced support, inthe present instance on the upper end of the stem 16 of a screw 17engaged in a screw threaded socket in the frame 1. The stem 16 of thescrew 17 also has Xed to it to rotate therewith a pinion 18 engaged bythe teeth of a horizontally reciprocating rack bar 19. Each ot the rolls2 and 5 have each of their end beaiiings similarly provided with crossheads and adjusting screws resting' on screws set in the main trame andeach ot these rolls has a rack bar corresponding to the rack bar 19which rests in recesses in the upper portions of the side trames ofthemachine and extend across so as to engage the. pinions 1S forsimultaneously operating` the two end bearings of a roll. The positionof the rack bar 19 with respectto these pinions at the opposite ends-ota roll, is clearly shown in Fig. 2.

The rack bar 19 and its companion rack bar have, on their ends,anti-friction wheels 2O and 21, which bear against the face of a camwheel 22. The face of the cam wheel 22 (see Fig. 7 is provided with twocams, denoted by 23 and 24:, adjustably secured in a circumferentialtrack on the face of the wheel by means of a curved elongated slot 25.The cam 23 is in position to engage the anti-friction wheel 21 and thecani 24.- is in position to engage the anti-friction wheel 20. The camwheel 22 is rotated by means of gear 26 fixed to rotate with the wheel,the gear 26 being driven by the pinion 27 operated in turn through asystem ot' gear from the drive pulley 10. As the cani wheel A2:2revolves, the cam 23 will first engage the wheel 21 and operate its rackbar longitudinally thereby turning the pinions corresponding t0 thepinions 1S and hence the screws corresponding to the screws 17 in adirection to turn the screws out of their threaded sockets .in the frame1, thereby lifting the roll 2 away from its companion roll 3. After theproper interval determined accurately by the adjustment of the cams and24- on the face of the wheel, the cam Q-L will engage the wheel Q0 andoperate its rack bar in a direction to lift the roll 5 away from itscompanion roll 4f. This operation of the rolls will prevent the rulingof the lines during the interval of time that the wheels Q1 and 2O areriding along the faces of their respective cams and when the said wheelsdrop olf these cams, the ruling will promptly begin.

The rack bar 19 and its companion are yieldingly held against the face`of the cam wheel and the cams thereon by a spring pressure device shownin detail in Fig. 6, where aspring 2S is fixed at one end to the fralne1 and its free end extends upwardly and presses against a pin Q9 on theside of therack bar, the throw of the rack bar toward the face of thecam wheel 22 being softened by means of a buffer 30 which may consist ofa felt or leather casing on a bracket 31 secured to the frame againstwhich buffer a block 32 on the side of the rack bar 19 opposite that onwhich the spring QS operates, is fixed. The spring 2S serves to promptlyreturn the rack bar after it has been forced to move longitudinally bythe cam 23 or 21 and in returning it with its anti-friction wheel intoengagementl with the face of the cam wheel, it turns the screws 1T inthe direction to lower the roll into position to continue the ruling.The paper to be ruled as it enters between the rolls Q and 3 may bedeflected away from the face of the roll Q by means of a guide 33 and inpassing from between the rolls Qv and 3 to the rolls 4e and 5 it may bedefiected by a. guide 3l away from the roll et, z'. e., the paper may bedirected away from the ruling rolls or rolls provided with the rulingdisks until it is actually forced into contact therewith by the rollwhich carries the grooves corresponding to the ruling disks. Ittherefore follows that when the ruling roll 2 is lifted away from thegroove roll 3, the paper will notreceive the impact of the ruling diskson the roll 2 and when the groove roll 5 is lifted away from the diskroll 4, the paper will not be forced by the said roll 5 into engagementwith the ruling disks on the roll el.

As the paper is fed from the tapes 8 it passes onto a lower guide 35through which project a series of toes or abutments 36 which momentarilyhold the front edge of the paper from advancing', causing it to squareitself if it is out of alinement and to begin its travel between theruling rolls at the proper intervals. These toes 36 are fixed on a rockshaft 37 which is operated by means of a cam 38 on the periphery of thecam wheel Q2, which cam comes at the proper intervals into engagementwith the dog 39 on the rock shaft 3T and rocks it to lift the toes 3Gabove the guide 35 and thereby prevent the sheet from moving onward,until the proper moment arrives for it to advance. The return of therock shaft 3T is provided for by a coil spring 40 surrounding the shaft3T, one end of the said spring being made fast to the shaft and theother to the frame of the machine. As the am 3S leaves the dog 39, thetoes 3G will move downwardly out of the way and the paper will advancetoward the ruling rolls. Before the paper reaches the ruling rolls, thecam will have engaged the wheel 21 and the roll 2 will be lifted toleave an unruled heading on the upper face of the sheet, the width ofwhich heading will depend upon the position of the cam Q3 in its grooveand the length of the'cam. In like manner, the roll 5 will be lifted bythe cam 2i before the paper reaches the ruling roll et and an unruledheading will be left on the under face of the sheet. It is importantthat the sheet start its advance movement promptly when the toes 36 dropand to insure this I provide a pair of auxiliary feed rolls 41, ft2,which engage the sheet with just sufiicient friction to advance it whenit is released but slip on its face while the sheet is obstructed by thetoes 36 without buckling it.

In operation, as the sheet of paper enters between the rolls 2 and 3,its upper face will be ruled from the head toward the foot and when itshead reaches the rolls et and 5, the ruling will begin at the properpoint on the under or opposite side of the sheet. Immediately followingthe stopping of the ruling of the upper face of the sheet, a new sheetwill be positioning itself ready to begin its advance for ruling on. theupper face and so on, the moment at which the succeeding sheet shall beintroduced being precisely determined by the cam 3S on the cam wheel 22,which cam releases the shaft 37 and takes the toes or abutments 3G outof the path of the sheet to permit it to enter between the rolls 2 and3.

that I claim is 1. In a ruling machine, a disk roll and its companionplaten roll, one of the said rolls being mounted in movable bearings,inclined faced supports for said movable bearings, means for adjustingthe bearings relative t0 the inclined faced supports, means foroperating the rolls, a traveling cam timed wit-h respect to the rolloperating means and means for transmitting motion from the traveling camto the inclined faced supports for operating the inclined faced supportsand hence the movable bearings to separate the rolls at predeterminedintervals.

2. In a ruling machine, a disk roll and its companion platen roll, oneof the said rolls being` mounted in movable bearings, screws formingsupports for said movable bearings, means for adjusting the bearingsrelative to the supporting screws, means for operating the rolls andmeans timed with respect to the roll operating` means for operating thescrews and hence the movable bearings to separate the rolls atpredetermined intervals.

3. In a ruling machine, a disk roll and its companion platen roll, oneof the said rolls being mounted in vertically sliding bearings, bearingscrews located at one side of the vertically sliding bearings, crossheads behind the bearings extending over the upper ends of said screws,adjusting screws extending through the heads and resting on the upperends of the aforesaid screws, means for operating the rolls and meansfor operating` the bearing` screws to raise and lower the sliding`bearings to separate the rolls at predetermined intervals. l

In testimony, that I claim the foregoing as my invention, I have signedmy naine in presence of two witnesses, this 30th day of April 1909.
